Abstract: The present invention relates to oxygen scavenging compositions comprising a) platelet particles having attached thereto at least one oxygen scavenging organic cation and b) at least oxidation catalyst. The oxygen scavenging compositions of the present invention may be readily incorporated into a variety of matrix polymers to create polymer composites which display improved passive barrier and oxygen scavenging capabilities. Articles formed from these composites are also disclosed.

Abstract: An apparatus for detecting an invisible, near infrared fluorescing mark disposed on a background comprises: an excitation source for exciting the mark, the source having sufficient power to provide a fluorescent signal from a mark situated on at least reflective portion of the background; signal detecting means for detecting the fluorescent signal from the mark; and power modulating means for varying the power between zero and the maximal power level of the excitation source, which is preferably a laser, in a manner effective to produce a decodable fluorescent signal from a mark disposed on any portion of the background. A process for decoding an invisible mark comprising a near infrared fluorescing material comprises: providing at least one invisible, near infrared fluorescing mark disposed on at least one portion of a background; exciting the mark with a laser having a maximal power level sufficient to provide a fluorescent signal from the mark when it is disposed on at least reflective portion of the background; and detecting the fluorescent signal and concurrently varying the power of the laser between zero and its maximal power, thereby obtaining a decodable fluorescent signal at a laser power level between zero and the maximal of a mark disposed on any portion of the background.

Abstract: The present invention relates to thermal transfer ribbons comprising a ribbon backing element and at least one printing media layer comprising at least one near infrared fluorescent compound in a concentration which provides detectable fluorescence without imparting color to a mark made from said printing media layer. Methods for printing marks containing said at least one near infrared fluorescent compound via thermal transfer and methods for reading said marks are also disclosed.
